Let's divide 818405 by 66
We're looking to find how many times 66 goes into 818405.

Moving on to step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 66

On to step 2:
If we divide 81 by 66, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 15 after subtracting 66 from 81.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 66

Let's proceed to step 3:
158 divided by 66 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 132 away from 158, we end up with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 66

Step 4:
When dividing 264 by 66, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtract 264 from 264 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 66

Step 5:
If we divide 0 by 66, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1240.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 66

Moving on to step 6:
If we divide 5 by 66, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 12400.0
Subtract 0 from 5 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 66 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 12400.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
66 goes into 500 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 12400.07
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 12400.075
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 12400.0757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
66 goes into 380 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 12400.07575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
If we divide 500 by 66, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 12400.075757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
66 goes into 380 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 12400.0757575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
66 goes into 500 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 12400.07575757
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 12400.07575757 with a remainder of 3.8e-08.
